- Using a named pipe and have `skabus-dyntee` read from it (and it dies as soon as the writer program ends).
Yes, that's normal. If you want to avoid this, you need to keep the named pipe open, and that can be done via having another process opening the named pipe for writing, and not dying. That process can even be the reader itself, see below.
- Configuring up s6-fdholder for my user to use (but it seems I don't understand how to give it the stdin to read).
You don't need a fdholder just for this: you already have a living process that can maintain the named pipe - skabus-dyntee itself. Try the following: exec <named-pipe exec 42>named-pipe exec skabus-dyntee args... (or in execline: redirfd -r 0 named-pipe redirfd -w 42 named-pipe skabus-dyntee args... ) -- Laurent
